Yes, just like pretty much all mammals.

Plant cells do need proteins to live/survive. They also make proteins.
No, you don't really need animal proteins to survive, because there are other types of protein you can have if you are a vegetarian, such as beans, tofu, and things similar to that. Hope this helped!
You need Carbohydrates, Proteins, Fats (Yes, Fats) Vitamins, Mineral Salts, and Fibre.
Your body doesn't necessarily need carbohydrates, as long as it can get its energy from proteins and fats. But consuming carbohydrates are the fastest way to give your body the energy it need to carry out its daily functions.
carbohydrates,lipids,proteins,and nucleic acids
I wonder that bird's wings need carbohydrates to move up and down. The wings of birds are constituted of muscles and those muscles need proteins and carbohydrates to function, and I am referring to the flying birds, not to the land-based birds, although their wings need carbohydrates and proteins as well.
It depends on the context. Colloquially, proteins and carbohydrates mean the polymers (polypeptides and polysaccharides) because there is no need to address the monomers - we eat the polymers. However, while studying Biochemistry, it is not sufficient to say just protein or carbohydrate. You would need to specify if your talking about a monomer or a polymer and what type.
human beings need nitrogen for building proteins and o2
Nitrogen is a essential element for buildic up proteins,Carbohydrates,Nucleic acids.
You need proteins, fats, carbohydrates, vitamins and minerals. Without balanced diet you may get many diseases.
You need proteins, fats, carbohydrates, minerals, vitamins, fibers and water in your diet. You have to take care of proteins. Carbohydrates fallow you in vegetarian diet. For the vitamins and minerals, you have to take fruits and vegetables. Fats make the food palatable. Fats give you lot of calories.
